You CANNOT get HIV from kissing. It just does not get transmitted that way. No way, no how. You are focusing on HIV, but if it wasn't that, you would find some other danger to focus on instead. Believe me, I know - I've done it myself. You need to work on getting your OCD under control. I know it's hard and will take some work, but it can be done. Follow the tips I recommended above and you will make progress.
I know it's hard to get the "yeah but what if" machine in your head to shut up but it can be done. Therapy, anti-anxiety drugs, exercise and distraction (keeping busy) can all be used to stop your brain from showering you with disturbing thoughts. Meditation is also very useful (or prayer, which is a form of meditation, if you are religious). You can re-program your brain to stop obsessing, but you have to work at it. It's worth the effort!
I know how you feel, I think I got it from a kiss. I know that's not possible,but it won't leave my mind! You are not alone!
I'm having that same fear, that I got HIV from a kiss. It want leave my mind!
If you were beyond the window period when you had both of your HIV test, then no, there is no chance they could both have been false-negative. The tests that are used these days are very accurate. The chances of one test being a false negative are very small so the chances of getting two false negative tests are non-existent.
You are suffering from OCD. There is part of your brain that is giving you false messages that you are in danger when you are clearly not. If you were to get tested a 3rd time, you would only be feeding your OCD - you might feel relief for a short time but then you would eventually start doubting that 3rd test result and think about getting a 4th.
OCD is no fun to have, but it is a medical problem the same as if you had diabetes, a heart condition or an ulcer. If you try to ignore it and don't do anything to treat it, it will just get worse. There is no "magic bullet" to get rid of OCD, but there are things you can do to help. Seeing a therapist (either a psychologist or psychiatrist) can help. You can talk about your fears and they can help you with them. There are several approaches to combating OCD. Medication is one of them, and can be quite effective but it is not the only way. Cognitive behavioral therapy is another approach that has been shown to be effective in treating OCD. Sometimes doctors will use a combination of treatments to help you.
If you are unable to see a therapist, there are a number of self-help books that you will find helpful. Some are even available in audiobook format that some people find helpful as it is read in a friendly voice that is different from your internal voice (which has been telling you all these false messages). Two that I like are "Worry" by Dr. Edward Hallowell and "You Are Not Your Brain" by doctors Jeffrey M. Schwartz and Rebecca Gladding.
Things you can do right away that will help are to get plenty of sleep, eat regular nutritious meals, exercise vigorously every day, pray or meditate and have regular social interaction (both to have someone to talk to about what is bothering you and to distract you from continuously thinking about it).
I had a night out which I dont really remember which I was out with a girl. Ive had every symptom under the sun but have also had 20 negative tests out to 9mths. I feel for ya man, its a nightmare
